Key to the success of any wine is the quality of the fruit. As is often the case, Carter does not grow its fruit but sources, or buys it, from some top vineyards. The Merlot comes from Truchard Vineyards in Napa’s Carneros district, hence the Truchard reference on the Carter label. The fruit is then crafted into its wonderful final form by Nils Venge, the winemaker, at his Saddleback Cellars.
